PENCIL.

Specification of Letters Patent.

Application tiled June 3, 1910. Serial No. 564,792.

To all whom it may concern Be it known that LHERMANN Rnrcrm, a citizen of the United States, and a resident of Millstone, in the county of Somerset and tState of New Jersey, have invented a new and Improved Pencil, of which the following` is a full, clear, and exact description.

his invention relates to certain improvements in pencils, and more particularly to that type of pencil in which the marking material is contained within an innerchamber or compartment and fed therefrom as required for use.

My invention relates particularly to the feeding and supporting means for the marking material, and the, main objects of my invention are to facilitate the delivery of the material, to sharpen the point of the ma` terial or to reduce the cross sectional area thereof as the material is delivered, and to accomplish this reducing 'or'sharpening action by a very simple form of mechanism.

A further important feature of my in` vention. is a storing of the erasing material or abrasive within the same pencil body with the stored marking material and to deliver the erasing material from said body as desired and by means of very simple mechanism. i The invention consists in the combination and arrangement of parts hereinafter parsimilar to a portion of Fig. 2, but taken in av plane at rightangles to Fig. 2; Fig. 4 is an end view of the cap or tip at the'delivery end of the pencil; Fig. 5 is a transverse section on the line 55 of Fig. 3; Fig. 6 is a transverse section on the `line 6-6 of Fig. 2,

,. but on an enlarged scale; Fig. 7 is a side ele` vation of theeraser delivering-member; Fig. 8 is' a side elevation of the pencil, the parts of the tip bein 'distorted to sharpen the marking materia and Fig. 9is an end view of the tip as shown in' Fig. 8.

5.5 'in theaccompanying drawings, I employv In the specific form of pencil illustrated a body portion 10, preferablytubular inform and .constructed of any suitable material, as, for instance, aluminum alloy. This tubular body is adapted to contain not only the marking material, but also the erasing material, and at opposite ends of the body are separate devices for individually delivering these materials for use. The erasing material is preferably in the form of a core or rofl 11 and is supported within an inner tube. or chamber 12, extendin lengthwise of the body 10 and concentricltherewith. The body 10 at one end, has a neck portion 13 of reduced diameter and the inner tube 12 has a neck portion 14 of slightly enlarged Adiameter and rigidly secured within the neck 13. This holds the body 10and the inner tube 12 in their proper relative positions, and prevents movement of one in respect tothe other. The tube 12 has an outwardly-extending bead 15 adjacent the inner end of the neck 13, and adjacent this bead the Wall of the tube is provided with inwardly-directed threads 16, which will engage with the outer surface of the erasing material and cause a relative longitudinal movement of the tube and erasing material when one is rotated in respect to the other.

Patented Aug. 4, 1914..

For rotating the erasing material, I provide the device shown particularly in Fig. 7. This device comprises a short tube 17 fttingwithin the neck 14v and having its inner end` split to form fingers 18, each of which has an outwardly-extending portion fitting into the bead toprevent relative longitudinal movement of the tube 12 and the feeding member 17. The feeding or delivering member 17 has an outwardly-extendinc,I fiange 19, preferably milled at its outer edge and disposed adjacent the ends of the neck portions 13 and 14. Beyond this milled flange is a guiding noz`zle or holder 2O for the erasing material. Intermediate the ends of the member 17 are two or more inwardlyextending, oppositely-disposed.; projections l or dogs 21, which may be formed by the `bending in of a portionof the wall of the member. These projections engage with grooves in the erasing material, so as to prevent relative rotary movement of the material and the member, but they are free to slide lengthwise of the material. By rotating the member 17 irl-respect to the body 10, the erasing material 11 1s rotated with the member and caused to `feed through the Aao threads 16 in a' direction dependent upon the direction of rotation of the member. Thus the material may be fed out or withdrawn to any extent desired.

At the opposite end of the pencil, there is provided a means for delivering the marli-v ing material and for sharpening and compressing` the same; As illustrated, the end of the bodylO is subdivided. by a series of longitudinally-extending slots, so as to form a series of prongs or ngers 22.A These ingers or 'prongs are elastic, and intermediate their ends they are concave. At the outer end ofeach ringer there is a bead or projection 23, which serves to hold a tip 24 in place. This tip has a substantially cylindrical portion 25 inclosing the prongs or fingers, and a conical portion terminating at its outer smaller end in a guide 26 through which the marking material is\ delivered. v Art the intersection of the cylindrical portion 25 and the conical portion, is an annu-y lar bead 27, into which the projections 23 extend, so as to prevent longitudinal movement of the tip on the body, but to permit free rotation of one in respect to t-he other. The tip along the length of the guide 26 and along a portion of the'length ofthe conical portion, is separated into two sections by oppositely-disposed, longitudinally-extending slots 28, the purpose of which will be set forth more'fully hereinafter.

Within the tip 24 is a plate 29 serving as a guide for the marking material, and also serving as a propeller for delivering the marking material to the guide. The plate is i preferably formed of sheet metal and ex- Jends lengthwise of the tip and substantially diametrically thereacross. The plate may have projections 30 for engagement with the slots 28, to prevent the rotation of the plate in respect to the tip. At its rear end, the plate is split into four separate fingers 31, 32, 33 and 34. rllhe two outer of these fingers, 31 and 34, are bent substantially at right angles, and engage with the ends of' the prongs or ngers 22 of the body, so as to prevent longitudinal movement of the platev in respectf to the body. The two intermediate fingers or prongs 32 and 33, ex.- tend lengthwise into the body between the fingers 22, and the ends are bent to form propeller vanes. rllhe vane 32 is somewhat longer than the vane 33, the dierence in length and the dierence inthe angle of inclination of the end, being dependent upon N the size and character of the material to be serve to receive the material and guide the guide 26.

License l Aabove theirst portion of the helix, and will tendto pull the coil lengthwise and guide the material to the series of `guiding grooves or loops 35, 36, 37 and 38, which direct the ymaterial lengthwise of the device in a straight line toward the outlet guides 26.

The several loops or guides 35, 36, 37 and 38 Idecrease in size from the beginning loop 35 to the terminal loop 38, so that as the material moves along the loops, it is compressed 85 .and reduced in cross sectional area, so that a lesser .quantity of the material has to be removed in sharpening the point. As the tip is rotated in the reverse direction, the vane 33 engages with the under side of the 9o last coil of the helix and draws the material back.

One important feature of my invention involves the sharpening of the point by the This guide, when the parts are in the normal position as indicated in Fig.

4, presents a tubular passage for the marking material, but by reason of the slots 28, the two opposite halves or sections of the guide may be moved llaterally in respect to each other, so as to bring one side of one section and the opposite side of the other section, toward the axial line of the pencil, as illustrated in Figs. 8 and 9. rlhese twoedges which are brought together, may have their inner edges sharpened or cut at an angle, so that when the parts are in the positions illustrated in Figs. 8 and 9, and the material is rotated within the guide by the rotation of the body Ain respect to the tip, the material will be sharpened and brought to a point. By releasing 'the' guide, the parts immediately return to thepositionshown in Fig. 4. The material may be :ladvanced without a sharpening action, by permitting the sections of the guide to remain in normal position, andl the material may be advanced or withdrawn by reversing the direction of rotation `of the body in respect to the tip. lin the sharpening device illus- 12o trated, thesections of the sharpening guide 26 arei integral with the remainderof the tip and the movement is due to the elasticity of the metal. lit is evident that the combined guide and Sharpener could be formed coil within the body, but it is evident that it might be supported in other ways.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: v
